What are the key features of TSM-122-02-F-DH-A-K-TR?
- 44-position dual-row SMT terminal strip on 0.100 inch (2.54 mm) standard pitch for broad connector compatibility
- Flat (F) SMT tail style optimized for co-planar surface-mount reflow soldering on tight pad geometries
- Dual-height (DH) insulator with polarization key (K) prevents incorrect mating in multi-connector assembly
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT production in high-volume manufacturing
What is TSM-122-02-F-DH-A-K-TR used for?
The TSM-122-02-F-DH-A-K-TR is suited to industrial I/O expansion cards, data acquisition boards, and embedded computing modules that require 44 signal positions in a compact 0.100-inch dual-row SMT footprint. Its flat SMT tail style ensures co-planarity across all 44 contacts during reflow, reducing solder-bridge risk on fine-pitch land patterns. The polarization key option protects against reversed cable insertion in field-serviceable instruments and control panels with multiple adjacent connectors.

Frequently Asked Questions
What does the F tail style mean for TSM-122-02-F-DH-A-K-TR, and how does it differ from SM or TL tails?
The F (flat) tail style in TSM-122-02-F-DH-A-K-TR refers to a flat SMT termination profile designed for co-planar soldering on the PCB surface. Unlike TL (through-hole tail) variants that require drilled holes, the F style is purely surface-mount and maintains all 44 contact tails within a tight co-planarity tolerance of less than 0.1 mm, ensuring full pad contact during reflow at peak temperatures up to 260°C for lead-free processes.
How does the 44-position dual-row layout of TSM-122-02-F-DH-A-K-TR reduce PCB footprint versus a single-row equivalent?
With 44 positions in dual-row format on 0.100-inch (2.54 mm) pitch, TSM-122-02-F-DH-A-K-TR spans approximately 54 mm in the row direction versus approximately 110 mm for a single-row 44-pin header at the same pitch. This 2x length reduction is significant for industrial I/O boards and backplane headers where multiple connectors must share limited board-edge space, enabling more connectors per PCB edge unit length.
Can TSM-122-02-F-DH-A-K-TR mate with standard 2.54 mm IDC ribbon cable assemblies used in industrial wiring?
Yes, TSM-122-02-F-DH-A-K-TR mates with standard 44-pin IDC ribbon cable connectors designed for 2.54 mm dual-row headers. The polarization key (K suffix) requires a corresponding keyed IDC socket to ensure correct insertion polarity, preventing reversed wiring in industrial field installations. When specified without the K suffix, standard unkeyed IDC assemblies also fit, but the key is recommended for any application with frequent connector mating and unmating.
Is TSM-122-02-F-DH-A-K-TR interchangeable with TSM-122-04-L-DH-A-K-TR for an existing PCB design?
TSM-122-02-F-DH-A-K-TR and TSM-122-04-L-DH-A-K-TR are not directly interchangeable without a PCB footprint revision. The F suffix uses flat SMT tails requiring a surface-mount pad pattern, while the L suffix uses right-angle through-hole tails requiring drill holes and a different pad layout. Both share the same 44-position, 2.54 mm dual-row mating interface, so only the PCB termination style changes, not the connector-to-cable or board-to-board interface geometry.
